Systems and methods for disinfection

ABSTRACT

A disinfecting system includes a housing. An ultraviolet light (UV) source is secured to the housing and configured to emit UV light for disinfection of a target. A processor is secured to the housing in communication with the UV light source. The processor is configured to activate the UV light source for a selected amount of time suitable for disinfection of the target.

BACKGROUND

The field of the disclosure generally relates to principles of disinfection—which may include one or more of sanitization, sterilization, and cleaning—debridement, treatment of tissue wound surfaces with agents, optical and acoustic treatments with or without pharmaceutical/chemotherapeutic agents. The individual treatment or combination treatment may enhance existing single module treatment for management of cleansing disinfection, wound tissue care, etc.

Generally, improperly disinfected (e.g., sterilized) objects can be harmful to patients and/or users as the objects can potentially transfer or spread harmful agents (e.g. bacteria). In some instances, deaths have been caused by improperly sterilized objects. For example, an amoeba was introduced to patients' brains by the use of nasal rinsing apparatus having contaminated water. Additionally, improperly sterilized medical instruments have been known to transmit drug-resistant bugs and/or bacteria in hospitals possibly due to a complete removal of a bioburden. There is a need for systems and methods of sterilizing objects used on or by patients.

DETAILED DESCRIPTION

The systems and methods described herein enable disinfecting of a target (e.g., one or more of an object, a surface, material, and matter) using ultraviolet (UV) light and/or ultrasound. As used herein, disinfecting and disinfection of the target means the ability to kill and/or destroy some or all infectious agent(s) at/on the target. Thus, disinfecting may include sterilization or sanitization, though not necessarily. The ultraviolet is configured to be effective in retarding growth, destroying, and/or killing infectious agents. As used herein, “infectious agent” or “infectious agents” refers to any organism that causes disease in a host including, but not limited to, a virus, bacterium, bacteria, prion, fungus, parasite, and disease (e.g. toxoplasmosis).

Ultraviolet light, such as ultraviolet C (UVC; i.e., electromagnetic radiation or light having a wavelength from about 100 nm to about 280 nm, such as 254 nm), has been known to have a microbicide and bactericidal effects on air, liquids, and surfaces. In some embodiments, a wavelength set to 254 nm is effective at eliminating bacteria (e.g. Naegleria fowleri) in the following lifecycle stages: Cyst, trophozoite, and flagellate. In such embodiments, the ultraviolet (UV) dosage utilized for the inactivation of the N. fowleri in water is 63 mW·sec/cm². Other electromagnetic radiation wavelengths may also be effective for disinfecting, sanitizing and/or sterilizing, including but not limited to wavelengths from about 270 nm to about 320 nm.

In one embodiment, ultraviolet light is transmitted in and around the embodiments described herein through an ultraviolet LED or LED array. In some embodiments, the LED is flexible and capable of flush securement on non-planar surfaces. Additionally, the LED array may be fabricated on a flexible strip. In some embodiments, a non-pulsed output is provided with the intensity controlled by a current limiting resistor in series with the LED. Alternatively, the UV light can be transmitted in any manner that facilitates sterilization as described herein, including but not limited to, a fluorescent UVC bulb and a laser. The ultraviolet LED(s) described herein can have a wavelength range of 100-400 nm. In some embodiments, a wavelength at 240-260 nm is preferred (i.e. for DNA absorption and/or bacteria/virus reduction), or at 365 nm (i.e. for water sterilization or treatment). Alternatively, the UVC described herein and used in various embodiments can scan in any suitable wavelength range that facilitates disinfection, sanitation, and/or sterilization as described herein. In the exemplary embodiment, a single or multiple sensors could be used to monitor temperature, power, pH, and/or other parameters needed to determine if the object that is subject to disinfection, sanitation, and/or sterilization is safe to use. The treatment time may be automated, and the movement of the UV light source and/or the object to be treated may be automated. For example, a robot or other device may automated movement of the UV light source and/or object to be treated.

FIG. 1 is a schematic diagram of a pulse-width modulation (PWM) LED driver circuit, generally indicated at reference numeral 100. Circuit 100 includes a processor 102 to control the output of the buck boost converter that drives the UV LED(s) 104 (e.g., UVC LED(s)). A switch is connected to the processor 102, which enables a user to set an intensity level of the UV LED(s). In some embodiments, circuit 100 is capable of driving high power UV LED(s). In the exemplary embodiment, the PWM UV LED is powered using a battery. Alternatively, the PWM UV LED can be powered by any known power source including, but not limited to, a DC power supply.

FIG. 2 is a schematic diagram of a 555 LED driver circuit, generally indicated at reference numeral 110, for use with the circuit 100 shown in FIG. 1. The circuit 110 includes a 555 timer to drive the UV LED(s) 104. The intensity level of the UV LED(s) can be controlled by tuning the frequency adjusting potentiometer 112. The driver 110 will be capable of driving lower power UV LED(s). In the exemplary embodiment, circuit 110 is powered using a battery. Alternatively, circuit 110 can be powered by any known power source including, but not limited to, a DC power supply.

In one embodiment, the battery used to power circuits 100 and 110 could be charged using AC\DC wall adapter or wireless charging technology. FIG. 3 is a schematic diagram of a wireless charging circuit 120 for use with circuits 100 and 110 shown in FIGS. 1 and 2. In the exemplary embodiment, circuit 120 utilizes a transformer, rectifier circuit, and LDO regulators to power a 555 timer oscillator circuit, such as circuit 110. The oscillator circuit drives an inductor that will be used to transmit an electromagnetic field to a receiving circuit. The inductor L2 and capacitor C9 values will be chosen to resonate at the same frequency of the 555 timer.

FIG. 4 is a schematic diagram of a wireless receiver circuit 130 for use with circuits 100, 110, and 120 shown in FIGS. 1-3. In the exemplary embodiment, circuit 130 includes a battery charger 132 that powered by the wireless receiver. The wireless receiving circuit also includes an inductor L5 and capacitor C15 which values will be chosen to resonate at the same frequency as the transmitter circuit. The half-wave rectifier and filter capacitor will be used to power the battery charger 132. Alternatively, the battery charger 132 can be powered using an AC/DC power source. In one embodiment, the battery charger 132 is used to charge the battery that powers the LED driver circuit 100.

In addition to the sterilization provided by UV, ultrasound can be combined with the UV to clean and/or sterilize objects. FIG. 5 is a schematic diagram of an ultrasonic drive circuit 140 that can be used with any combination of circuits 100, 110, 120, and 130 shown in FIGS. 1-4. In one aspect, ultrasonic acoustic waves pass through liquids, such as water, causing cavitation. Cavitation is the formation of small high pressure bubbles. When the bubbles implode or explode the high level of pressure and heat is exerted onto nearby surfaces. Cavitation can be used to disrupt and destroy infectious agents on, in, and/or around an object. Additionally, ultrasound can be used to disrupt intercellular communication which can prevent growth of and break apart infectious agents without the use of cavitation.

In some embodiments, a frequency range of the ultrasound is adjusted to target specific infectious agents. In one embodiment, the ultrasound is adjusted in the frequency range from 20 kHz to 3 MHz. Alternatively, the frequency range can be any range that facilitates sterilization as described herein. In the exemplary embodiment, the drive signal is selected to have a predetermined output based on the target object. For example, the predetermined output of the drive signal can be constant, pulsed, and/or modulated to obtain the desired results. The ultrasonic device can be made of many different constructions including, but not limited to, bolt clamped Langevin or piezoelectric discs. In some embodiments, one or more sensors are used to monitor at least one of temperature, power, pH, and other parameters needed to determine if the ultrasound is or has been effective in sterilizing an object.

In the exemplary embodiment, circuit 140 includes a processor 142 to control the drive signal of an ultrasonic transducer. The push-pull design consist of two mosfets being switch to cause a push and pull of current through the primary side of the transformer. The center tap on the primary side of the transformer determines amplitude on the secondary side of the transformer. The inductor on the secondary side of the transformer will be used for impedance matching to allow for efficient power consumption. Other drive circuits as known in the art can be utilized.

It should be noted that processors described herein may include one or more processing units (e.g., in a multi-core configuration). Further, processors described herein may be implemented using one or more heterogeneous processor systems in which a main processor is present with secondary processors on a single chip. As another illustrative example, the processors may be a symmetric multi-processor system containing multiple processors of the same type. Further, the processors may be implemented using any suitable programmable circuit including one or more systems and microcontrollers, microprocessors, reduced instruction set circuits (RISC), application specific integrated circuits (ASIC), programmable logic circuits, field programmable gate arrays (FPGA), and any other circuit capable of executing the functions described herein. Additionally, the processors may perform partial processing and receive partial processing by a processor and/or computing device communicatively coupled to the processors.

FIG. 6 is a perspective view of an exemplary nasal cavity fluid dispenser 200 for use with any combination of circuits 100, 110, 120, 130, and 140 shown in FIGS. 1-5. In one embodiment, dispenser 200 is configured to disperse fluid into a nasal cavity for nasal irrigation (e.g. Neti pot). In the exemplary embodiment, dispenser 200 includes a main body 202, fluid reservoir 204, and a fluid entry aperture 206. Connected to the main body 202 is a handle 208, a neck 210, and a fluid exit aperture 212 coupled to the neck 210. In one embodiment, dispenser 200 includes a filter 214 that is removably coupled in aperture 206.

Filter 214 is configured to remove infectious agents from the fluid provided to dispenser 200. Filter 214 can have any media for filtering fluid including but not limited to, ceramic, ceramic with carbon core, glass fiber, a structured matrix, and iodine resin. In the exemplary embodiment, filter 214 is manufactured with a pore size of 1 micron or smaller. Alternatively, filter 214 can have any pore size that facilitates sterilization as described herein. In some embodiments, filter 214 is fixedly coupled inside of dispenser 214. Filter 214 may have a UVC light source incorporated into the filter 214 to ensure dispenser 200 is sanitized.

In the exemplary embodiment, dispenser 200 includes a base 220. Coupled within base 220 is a UV light source 222. In some embodiments, an ultrasound transducer 224 is coupled within base 220. In some embodiments, light source 222 is an ultraviolet LED or LED array. Alternatively, light source 222 can be any light source that provides UVC waves, including but not limited to, a fluorescent UVC bulb and a laser. A light amplifying device may be adjacent the light source 222 to amplify its output. For example, the light from the light source 222 may be amplified by a Fresnel lens or other optic. Transducer 224 is configured to provide ultrasound to fluid retained in reservoir 204. In one embodiment, base 220 is sealed from fluid reservoir 204, such that fluid in reservoir 204 cannot contact light source 222 and/or transducer 224. Alternatively, base 220 is open to reservoir 204 to enable fluid in reservoir 204 to contact light source 222 and/or transducer 224.

In one embodiment, light source 222 and/or transducer 224 are powered and run by circuits (e.g. circuits 100, 110, 120, 130, and 140) coupled in base 220. In such an embodiment, a power source 226, including but not limited to, a battery, is the source of power. In an alternative embodiment, dispenser 200 is configured to have power received on a docking station 230. Docking station 230 includes a transmitter 232 for providing power to power source 226. In one embodiment, power is supplied from transmitter 232 to power source 226 wirelessly through induction. Alternatively, power can be supplied from transmitter 232 to power source 226 in any manner that facilitates power transfer.

Utilizing light source 222 and/or transducer enables dispenser 200 to sanitize fluid within the dispenser and/or the inner walls of the dispenser. Treating and/or sanitizing water prior to using dispenser 200 will reduce the risk of being infected with infectious agents (e.g. the PAM disease). In one embodiment, the fluid (e.g. water) is treated for a specified amount of time with the light source 222 before use of dispenser 200. In some embodiments, the fluid (e.g. water) is treated for a specified amount of time with ultrasound emitted from transducer 224 before use of dispenser 200. The treatment times of UV and/or ultrasound and the frequencies of the ultrasound can be specified to target a specific infectious agent. In one example, the light source 222 and the ultrasound transducer 224 may be operated simultaneously to disinfect the dispenser 200. Bubbles in the fluid caused by the ultrasound transducer 224 may assist disinfection by the light source 222. In another example, the light source 222 and the ultrasound transducer 224 may be used at different times, independent of one another. Additionally, the light source 222 could also be used to sanitize the dispenser 200 after each use. In some embodiments, one or more sensors 240 are positioned in dispenser 200 to monitor at least one of temperature, power, pH, and other parameters needed to determine if the UV and/or ultrasound is or has been effective in sterilizing the dispenser 200 and/or the fluid within the dispenser 200.

In one embodiment, an electrical current is transmitted to fluid in reservoir 204 to disrupt any infectious agents present in the fluid. In such and embodiment, positive and negative electrodes are integrated into reservoir 204 and/or base 220 and an electrical current is conducted through the fluid before use of dispenser 200. Dispenser 200 can be configured to supply either or both of AC and DC current to the fluid prior to use.

FIG. 7 is a perspective view of an object sanitizer 300 for use with any combination of circuits 100, 110, 120, 130, and 140 shown in FIGS. 1-5. In the exemplary embodiment, sanitizer 300 is configured to be located in a sterile environment (e.g. medical facility or food processing facility). Sanitizer 300 includes a housing 302 having one or more light sources 304 positioned in the housing. In some embodiments, light source 304 is an ultraviolet LED or LED array. Alternatively, light source 304 can be any light source that provides UVC waves, including but not limited to, a fluorescent UVC bulb and a laser. In one embodiment, light source 304 is configured to provide nutrients (e.g. vitamin D) to food placed in contact with the UV light emitted from light source 304.

Housing 302 also includes a viewable shield 306. Shield 306 is configured to protect users from UV light transmitted in housing 302. In some embodiments, shield 306 is a window that is polarized to allow a user to see into sanitizer 300 and not be exposed to UV light. Alternatively, shield may be have an opaqueness that blocks UV light while enabling a user to see objects placed in sanitizer 300. Shield 306 can be fabricated from any material capable of blocking UV light and permitting a user to see though the shield, including but not limited to glass and plastic.

In the exemplary embodiment, sanitizer 300 includes a bath 308 for retaining objects and fluid. In some embodiments, bath 308 includes a transducer 310 configured to provide ultrasound to fluid retained in bath 308. Transducer 310 is configured to provide vibratory energy (i.e. ultrasound) to the fluid in bath 308 to aid in dislodging and/or removing debris from objects placed in bath 308. For example, in a surgical setting, tissue and/or surgical debris that has attached to surgical instruments can be removed in a hands free manner. Likewise, in a food preparation setting, organic or inorganic material that has attached to food products can be removed from the food product by the vibratory energy transmitted through bath 308.

In some embodiments, sanitizer 300 includes a door 312 for inserting and removing objects subject to sterilization. In one embodiment, door 312 is also a shield 306. In some embodiments, a conveyer belt 314 is used in conjunction with sanitizer 300 to bring objects into and out of exposure with UV light transmitted by light source 304. Conveyer belt 314 can be configured to extend though bath 308, thus allowing objects placed on belt 314 to be exposed to ultrasound in a fluid environment. Alternatively, belt 314 can be configured to only provide UV light exposure to objects placed on belt 314. In some embodiments, one or more sensors 320 are positioned in sanitizer 300 to monitor at least one of temperature, power, pH, and other parameters needed to determine if the UV and/or ultrasound is or has been effective in sterilizing the sanitizer 300 and/or the fluid within the bath 308.

In one embodiment, sanitizer 300 is configured to sanitize fluid that is channeled through a tubular structure 320. In such an embodiment, tubular structure 320 can be coupled to a pump 322 configured to channel fluid through structure 320 and sanitizer 300. In one embodiment, the fluid channeled through structure 320 is blood extracted from a patient. This would enable blood to be sanitized and/or cleansed with UV and/or ultrasound. Such treatment would disrupt and/or kill infectious agents present in blood without killing red blood cells. In an alternative embodiment, sanitizer 300 can be utilized in conjunction with any hose system including, but not limited to, dialysis machines, heart-lung machines, coffee pots, humidifiers, jewelry cleaners, parts cleaners, foot baths, whirlpools, bath tubs, swimming pools, wax baths, pet food bowls, RV water tank, water heater, HVAC systems, refrigerators, dishwashers, as well as tanks and hoses in the fermentation of alcohol. As such, an ultrasonic signal could be transmitted through the lines that beer and fermented beverages are ran through in bars and restaurants to prevent the build-up biofilm and keep the lines clean by providing vibratory energy that would prevent blockage and preserve the beverage (e.g. preserve beverage integrity).

In the exemplary embodiment, fluid is channeled through sanitizer 300 by pump 322 at a time increment that will enable the fluid within structure 320 to be exposed to UV and/or ultrasound for a duration long enough to have a deleterious effect on infectious agents in the fluid. In some embodiments, the rate of speed of the fluid being channeled is selected based on the fluid flowing through structure 320. Alternatively, the rate of speed of the fluid being channeled is selected based on the infectious agent that is to be treated and/or eliminated such that the fluid is exposed to the UV and/or ultrasound for the predetermined time. The tubular structure 320 and/or the light source 304 may be movable (e.g., rotatable or oscillatable) to ensure the fluid in the tubular structure is exposed to the UV light from the light source as it flows through the tubular structure. In the same or another embodiment, the fluid in the tubular structure 320 may swirl around within the tubular structure. A device for causing swirling of the fluid flow in the tubular structure 320 may be provided.

FIG. 8 is a perspective view of an exemplary glove sanitizing system 400 for use with any combination of circuits 100, 110, 120, 130, and 140 shown in FIGS. 1-5. System 400 includes a glove sanitizer 401 having a housing 402 with one or more light sources 404 positioned in the housing. In some embodiments, light source 404 is an ultraviolet LED or LED array. Alternatively, light source 404 can be any light source that provides UVC waves, including but not limited to, a fluorescent UVC bulb and a laser.

In the exemplary embodiment, housing 402 includes an aperture 406 configured to enable a user wearing gloves to insert the gloves into housing 402 to enable exposure of the gloves to UV emitted by light source 404. The illustrated glove sanitizer 401 includes upper and lower UV light sources 404, whereby the users hands are positionable between the upper and lower light sources. The glove sanitizer 401 may be configured to activate the light sources 404 for a specified period of time (i.e., a timer) and/or communicate instructions to the user. A microprocessor may operate the glove sanitizer 401. In some embodiments, a sanitizing spray nozzle 410 is coupled in housing 402 to provide fluid disbursement to objects placed in glove sanitizer 401. In such an embodiment, nozzle 410 is coupled to a fluid reservoir 412 positioned in housing 402. Nozzle 410 is configured to provide a sanitizing agent to objects in glove sanitizer 401. In one embodiment, an alcohol based solution is ejected from nozzle 410. Alternatively, any sanitizing agent can be transmitted from nozzle 410 that facilitates sanitizing as described herein.

In the exemplary embodiment, system 400 includes a disposable glove 420 for use with glove sanitizer 401. Glove 420 can be manufactured from any suitable material including but not limited to, latex, nitrile rubber, vinyl, and neoprene. In some embodiments, glove 420 includes a coating to lubricate the gloves, making them easier to put on the hands. In the exemplary embodiment, glove 420 is fabricated to have an opaqueness that blocks UV light from being transmitted to the skin of a wearer. System 400 enables a user to sanitize a glove that would normally require disposal. For example, a medical professional could utilize 1 set of gloves 420 for examining different patients with the use of glove sanitizer 401 to sanitize the gloves between patients. Likewise, a user in a food processing facility would be able use 1 set of gloves between different foods with the use of glove sanitizer 401 to sanitize the gloves between work areas. System 400 provides cost effective way to prevent infectious agent transmission with a decrease in waste. Such a system would also enable health care professionals to potentially avoid the requirements of constant use of sterilizing agents on the skin. The glove sanitizer 401 may include a shield to inhibit a user's eyes from being exposed to UV light.

Alternatively, light source 222 can be any light source that provides UVC waves, including but not limited to, a fluorescent UVC bulb and a laser. In one embodiment, second light source 222 is coupled to a second light power source 712 positioned in base 702. Power source 712 is configured to receive and store current flowing into and/or through contact 706 and/or the ballast including but not limited to a super-cap and a battery.

In operation, when power is supplied to light 700, first light source 708 is powered from the current supplied and the second light power source 712 is charged. When power to light 700 is stopped, second light source 710 is powered by power source 712. For example, if light 700 were placed inside a refrigerator, when a door to the refrigerator opened, first light source 708 would illuminate the inside of the refrigerator and when the door closed, UVC would be provided to the inside of the refrigerator to sterilize food items and/or the refrigerator itself.

It should be noted that light 700 could be connected to a sensor that would provide signals for providing and eliminating UVC light. For example, light 700 could be configured to be placed above kitchen counters and only emit UVC when no motion is detected by one or more motion detection sensors. Additionally, second light source 708 can be on a flexible line 720 coupled to light 700 that enables a user to position and/or direct the UVC to a desired location.

Likewise, the application is configured to receive information from sanitizers 1304 and 1402 and sensors associated with device 1302 and 1402 to provide execution instructions. For example, a user may select to run a sanitizing protocol for kitchen counters. The application would determine the amount, power, and duration of UVC needed to kill infectious agents associated with kitchen counters. The sanitizers 1304 and 1402 can be associated with a robot or other device for automatically moving the sanitizers during treatment session. It should be noted that infectious agent data could be pulled from a data source retained locally on device 1302 and 1404 or on a remote storage location that is communicatively coupled to the device.

Once the application has determined the amount, power, and duration of UVC required for a particular protocol, a session is initiated or held until a user interacts with device (e.g. starts the session). During the session, sensors (e.g. accelerometer, magnetometer, gyroscope, proximity sensor, and camera) in device 1302 and 1402 are utilized to provide feedback as to the effectiveness of the session. The application can alert a user as to whether a surface and/or object has been in contact with a surface long enough to be sterilized and/or if a rate of speed of the sanitizer 1304 and 1402 is too fast or too slow to achieve a desired result.

Generally, UVC 260-340 nm can disrupt both DNA and RNA. This requires a specific direct line of site as well as a specific type. It has a depth of penetration. Treatment modalities would require this direct line of sight, specific time interval, depth of penetration, and specific exposure. This could be done through direct light, reflective light, specific movement or compression of the material so it becomes closer to the light source.

In addition, acoustic therapy/ultrasound can provide vibratory/debridement type treatment. This treatment in combination with UVC or in isolation may allow debridement material where similar modules can be removed or separated in existing ultrasonic cleaner or can be utilized in combination with chemical agents or pharmaceutical agents. Ultrasound may also have the potential to affect permeability of cell walls, membrane, i.e. bacterial cell walls, or blood brain barriers for example in dura which may enhance penetration of existing pharmaceutical or chemotherapy agents or chemical agents to enhance the ability to sterilize or clean tissue. Also the vibratory component may allow in combination with UVC less time or more direct light exposure.

UVC can be applied to traditional light, LED with battery operated, or laser to increase the depth of penetration. UVC can be battery powered or externally powered through electromagenetic waves to allow implantable device to be turned on or off. Ultraviolet light can have deleterious effects to other tissue as it can affect DNA and RNA. Pharmaceutical or other materials and/or chemicals, such as H₂O₂, may be added to the surface being treated.

The light optical or acoustic also has a depth of penetration, intensity of the light and duration. It could be integrated via computer and software programs to be able to turn on and off or be mobile. In addition, UVC and/or ultrasonic can be applied via robotic mechanism so they can be selectively moved whether in the body, in a room or specific space with a timer and location so one can provide timing/direct light of sight (reflective sight) or movement closer or farther as needed to enhance sterilization for topical effect. UVC could be applied via robotic control such as robotic floor cleaner or surface cleaner or via remote control drone type of device. It could also have motion sensors that could allow when movement is detected to be turned on or off so it is not damaging any living tissue in animals, people, etc.

This single or composite treatment may have use of pharmaceuticals (i.e. antibiotics or bacteriocidal) or can enhance the efficacy of the effect of pharmaceutical by applying UVC, ultrasound treatment, composite treatment, acoustic treatment, and/or optical treatment to enhance the efficacy of target agent for pharmaceutical. For example, ultrasound may open the cell wall membranes or bacterial wall membranes previously persistent antibiotics now can become toxic to the bacteria via the application of UVC or acoustic/ultrasound phenomenon. Vibratory or optical treatments may open the cell wall membranes to allow pharmaceutical/chemical agents to penetrate where previously the bacteria or cells were resistance to this and allow better depth of penetration. Resistant pharmaceutical agents may now become toxic to the bacteria, viruses, parasites, etc. Individuals could wear shields to eyes such as specific sunglasses to tune out UV or it could be motion censored or detect heat/movement to turn on or off either via remote control or via computer control. This could be linked to a control system that could also allow local pharmaceutical/chemotherapeutic agents whether inside the body or on a specific surface. We could also time so that chemical agents and/or UVC could be administered simultaneously i.e. spraying 60% alcohol and/or H₂O₂ as well as UVC at the same time so it would coat a body surface to sterilize it. This could be used for example for gloves which are placed on individual's hands. The gloves could have an optical shield in them so the UVC would not penetrate through the gloves. The individual would wear gloves and for example work on a patient rather than changing gloves and going to the next patient. They would go under a shield where UVC would be applied and then spray 60% alcohol or greater preparation that would further sterilize the gloves. These would also be dried and then one could go on to the next patient. This would prevent damage to the skin as the gloves would be on and the gloves would have an opaque surface for UVC so that UVC would not penetrate through the skin with addition of alcohol or chemical agent to further sterilize from above and below so circumferential treatment of gloves so one would not have to change gloves constantly. The gloves intrinsically would have an agent that would prevent penetration of UVC into the skin or tissue. As UVC is applied, it would either be shielded or be opaque so one would simply scan their hands for a known period of time underneath this for light and/or chemical agent to be sprayed on. Either the movement alone would allow drying or there could be a small burst of air with fan, etc. that would dry this. The combination of two agents would then allow the gloves to be sterilized so that one would not have to change the gloves and can keep the gloves on when going from patient-to-patient or treatment-to-treatment with preparation, etc.

If one has solid debris, one could place it in a vibratory ultrasonic bath. The ultrasonic bath could have chemical agents in it, pharmaceutical agents, etc. or could simply vibrate the material. One could then pass under UVC so composite treatments would not only debride and move material but then also sterilize UVC. It also affects not just bacteria but would affect viruses, parasites, or any material that is RNA/DNA. There would need to be a specific type typically in range of second and then with or without chemical or pharmaceutical spray and then we would be able to utilize.

This could also be applied for example in the eye. Currently, Toxoplasma gondii is a toxic infection in the eye and can permanently damage retinal cells. Antibiotics have trouble going to the blood brain barrier and there is no treatment as these agents can hide within the parasites/toxoplasmosis. With UVC/laser, one could go through the eye and treat the parasites for a period of a second or two. It would focus on specific lesions that may have active parasites and selectively kill these. Otherwise, it is extremely difficult to assess. Otherwise, these are permanent parasites. This could also be used for target laser and other type of parasites. It would not allow visualization but endoscopically for example light source could be applied to the liver, cranial tissue, brain tissue, liver tissue, etc. where parasites/viruses live permanently. This could be effective for herpes type viruses and neurologic tissue and specifically target the parasitic DNA. Specific timers and energy frequencies could be utilized to avoid damaging body tissue while specifically focusing on RNA or DNA of the parasitic tissue, viral tissue, or bacteria. Again, this could be used with known pharmaceutical treatment or could be used in isolation. The vibratory or acoustic components could also be applied to provide further access especially if there is fluid or gelatin media could be applied. This could be staged or simultaneous.

If one is adopting the pill or agent which could be implanted or swallowed to effect local tissue, the acoustic/optical energy UVC could be turned on or off as needed. There could also be remote control so the pill could be sped up or slowed down for example to adjust the system rather than allowing normal parasitosis to push the pill through the digestive system. This could be slowed by external wavelengths or radiofrequency so they can move either with parasitosis faster or slower so it could target a specific location. There could also be timer for turning the acoustic/optical energy UVC on and/or off.

This could be implanted in the peritoneum. For example, it could be guided in the peritoneum either robotically or magnetically to a specific location for a specific period of time. This would allow optical/acoustic energy. This could also time release a pharmaceutical agent as well so this could be timed and moved to another location. This could be done under endoscopic guidance during a surgical procedure or this could be implanted surgically and then applied at specific intervals. Later, this device could be tracked and then removed either by MRI, x-ray, ultrasound, or other diagnostic. This could be implanted laparoscopically, endoscopically, arthroscopically into the joint. It could be used, for example, arthroscopically into a joint if one has calcium (chondrocalcinosis crystals) that coat the joint one could use this to move through the joint and selectively remove the calcium crystals from the articular cartilage. This could be selectively removed with vibratory frequencies over a period of time so it would not damage the articular cartilage cells but acoustically, optically, chemically, or with pharmaceutical agents could selectively release the calcium crystals so they can move to the articular cartilage. One could have articular cartilage previously damaged via coating of chondrocalcinosis crystals. This would selectively vibrate and remove the crystals. There are different modules or elasticity of calcium which would selectively be removed and then potentially be flushed out again through a surgical procedure or could be left inside the joint. As one moves, it could selectively go through different parts of the joint and selectively move either from cartilage, synovial tissue, etc. This could target other known coating agents i.e. biofilm. Biofilm has different module so elasticity and biofilm can separate from tissue such as a joint replacement. Acoustic energy with or without UVC could be applied. Again, this could be implanted, removed, placed during endoscopic or arthroscopic procedure. It could then be selectively turned on and off to selectively remove the biofilm, chondrocalcinosis, or other material coating from metallic implant, polymeric implant, or biologic tissue since they are different modules and different material. They would selectively separate. This could be flushed out with chemotherapy or pharmaceutical agents. This could also be used to separate tumor which is a rapidly growing cell that is typically stiffer, harder, and firmer than local tissue. One could use the UVC, ultrasound, and/or chemotherapeutic agents to selectively kill the stiffer tissue i.e. rapidly growing neoplasm/cancerous tissue. Since it is rapidly growing, DNA is more affected by UVC and RNA affected by UVC ultrasound, chemotherapeutic agents where this could be targeted and turned on/off selectively as diagnostic portion of ultrasound will measure the density of the tissue. The acoustic portion of ultrasound will separate the two and then either ultrasound UVC and/or chemotherapeutic agent applied locally to kill neoplastic tissue. This could then selectively be turned on/off depending on the diagnostic portion of the ultrasound which in frequency determines there is a slime i.e. biofilm, chondrocalcinosis, crystallin type tissue, or denser tissue i.e. rapidly growing tumor tissue that has different acoustic density or diagnostic density via MRI or other diagnostic test. This could be selectively turned on and off with implantable or surgically operated device. This could be robotically controlled externally. Other treatments can also be applied, including laser (optical), electrical (RF), mechanical (pressure, torque), ESW, chemical (ETOH, H₂O₂), and pharmaceutical (pH/acid based).

Examples of this are implied in other patents i.e. Bonutti Robotics, Bonutti MIS patents which we reference by incorporation.

This also could be applied locally to tissue or locally to surfaces via wireless or mobile phone—Smartphone technology. UVC could be built on or application for your mobile phone where a selective wavelength could be used via cellphone, mobile device, Ipad, etc. to treat a specific surface. There would be a timer, location, depth. It would measure the distance from a specific surface. It would turn this on or off. It would be shielded so it would not develop direct eye contact. It could sterilize, cleanse, treat surface via UVC and mobile phone. Mobile application could also be used as a treatment device to turn on/off implantable device within the human body for sterilization treatment, chemotherapy, treatment of biofilm, etc. It could potentially be used to power the device. Chemotherapy agents or pharmaceutical agents could be applied by spraying, direct pressure, or solution to specific tissue as well.
